Treatment of Acute Otitis Media
High-dose amoxicillin (80-90 mg/kg per day in 2 divided doses) is the recommended first-line treatment for acute otitis media in most patients due to its effectiveness against common pathogens, safety profile, low cost, acceptable taste, and narrow microbiologic spectrum. 1
Diagnosis Criteria
Before initiating treatment, confirm the diagnosis of acute otitis media (AOM) by verifying:
- Acute onset of signs and symptoms
- Presence of middle ear effusion
- Signs of middle ear inflammation
- Symptoms such as pain, irritability, or fever 1, 2
Treatment Algorithm
First-line Treatment:
- High-dose amoxicillin: 80-90 mg/kg per day in 2 divided doses for:
- Children <2 years: 10-day course
- Children 2-5 years with mild/moderate symptoms: 7-day course
- Children ≥6 years: 10-day course 1
Alternative First-line Treatment (specific situations):
- Amoxicillin-clavulanate (90 mg/kg/day of amoxicillin with 6.4 mg/kg/day of clavulanate in 2 divided doses) for:
- Children who have taken amoxicillin in the previous 30 days
- Patients with concurrent conjunctivitis
- When coverage for M. catarrhalis is desired 1
For Penicillin Allergy:
Non-type I hypersensitivity reactions:
- Cefdinir (14 mg/kg/day in 1-2 doses)
- Cefuroxime (30 mg/kg/day in 2 divided doses)
- Cefpodoxime (10 mg/kg/day in 2 divided doses) 1
Type I hypersensitivity reactions:
- Clindamycin (30-40 mg/kg/day in 3 divided doses) 1
Treatment Failure (symptoms persist after 48-72 hours):
- Reexamine to confirm AOM diagnosis
- If initially treated with amoxicillin, switch to:
- Amoxicillin-clavulanate (90 mg/kg/day of amoxicillin with 6.4 mg/kg/day of clavulanate)
- If initially treated with amoxicillin-clavulanate, consider:
- Ceftriaxone (50 mg IM or IV daily for 3 days) 1
Second Treatment Failure:
- Consider tympanocentesis for culture and susceptibility testing
- If tympanocentesis not available, consider:
- Clindamycin (with or without a third-generation cephalosporin)
- Consult with otolaryngology or infectious disease specialist 1
Pain Management
Pain management should be addressed regardless of whether antibiotics are prescribed:
- Acetaminophen or ibuprofen for pain relief
- Topical analgesics may provide additional relief 1
Observation Option
In certain cases, observation without immediate antibiotics may be appropriate:
- Children ≥6 months to <2 years with non-severe illness and uncertain diagnosis
- Children ≥2 years without severe symptoms
- Reliable follow-up must be assured
- Provide analgesia and reassess in 48-72 hours 1
Follow-up Considerations
- Routine follow-up visits are not necessary for all children with AOM
- Consider follow-up for:
- Young children with severe symptoms
- Children with recurrent AOM
- When specifically requested by parents 1
Common Pitfalls to Avoid
Misdiagnosis: Differentiate AOM from otitis media with effusion (OME), which does not require antibiotics 1, 2
Overtreatment: Persistent middle ear effusion after successful treatment is common (60-70% at 2 weeks) and represents OME, not treatment failure 1
Inadequate dosing: Using standard-dose amoxicillin may be insufficient for resistant S. pneumoniae; high-dose is recommended 3
Inappropriate second-line choices: When amoxicillin fails, trimethoprim-sulfamethoxazole and erythromycin-sulfisoxazole are not appropriate due to high resistance rates 1
Neglecting pain management: Pain relief should be addressed regardless of antibiotic prescription 1
The treatment approach should consider the increasing prevalence of antibiotic-resistant pathogens, particularly penicillin-resistant S. pneumoniae and beta-lactamase-producing H. influenzae, which are the main reasons for treatment failure 1, 4.
